However, the presentdisclosure is not limited to the embodiment described below or thetechnical features of the present disclosure are not limited by thedescribed embodiments, and the present disclosure may be variouslymodified without departing from the technical scope of the presentdisclosure.

First Embodiment

FIG. 1 is a cross-sectional view illustrating a lamp for a vehicleaccording to a first embodiment of the present disclosure.

Referring to FIG. 1 , a lamp 10 for a vehicle according to a firstembodiment of the present disclosure includes a board part 30, a lightsource part 40, a lens part 50, and a reflection part 60. Furthermore,the lamp 10 for a vehicle according to the first embodiment of thepresent disclosure may further include an inner lens 70 and a housing20.

The board part 30 may be a printed circuit board (PCB).

The light source part 40 includes a plurality of light sources 41 thatare disposed on an upper side of the board part 30 and irradiate light.Various elements or devices, which may emit light, may be used for thelight source part 40. For example, the light source 41 may be a lightemitting diode (hereinafter, an LED).

The lens part 50 is installed to surround the light source part 40 andis disposed on an upper surface of the board part 30. The lens part 50is formed to be filled between the board part 30 and a reflectivesurface 61 of the reflection part 60. That is, a lower surface of thelens part 50 may be formed to contact the board part 30 and one surfacethereof may be formed to contact the reflective surface 61 of thereflection part 60. A shape of the lens part 50 may be changed accordingto shapes of the board part 30 and the reflection part 60.

The reflection part 60 is installed on an upper side of the board part30, and includes the reflective surface 61 that reflects the lightirradiated from the light source part 40 to change a travel path of thelight.

Furthermore, the reflective surface 61 is configured to contact the lenspart 50, and phosphor 63 is deposited thereon.

In detail, a phosphor layer 63 may be formed on the reflective surface61 of the reflection part 60, which contacts the lens part. A method fordepositing the phosphor 63 in the reflection part 60 is not limited. Forexample, after the phosphor layer 63 is manufactured and the reflectionpart 60 is injection-molded, the manufactured phosphor layer 63 may beattached on a rear surface of the reflection part 60. Alternatively, forexample, after injection-molding the reflection part 60, the phosphor 63may be deposited by applying the phosphor 63 on the reflective surface61 through coating. For example, the reflection part 60 may be formed ofa polycarbonate material, but the present disclosure is not limitedthereto.

Accordingly, according to an embodiment of the present disclosure, thephosphor 63 may be efficiently implemented without adding a separateprocess by depositing the phosphor 63 on the reflective surface 61 whenthe reflection part 60 is injection-molded.

Furthermore, according to an embodiment of the present disclosure, auniformity of the light may be enhanced by depositing the phosphor 63 onthe reflective surface 61, and images may be differentiated.

Furthermore, according to an embodiment of the present disclosure,optical patterns having various wavelengths and colors may beimplemented by varying a color of the phosphor 63 deposited on thereflective surface 61 when the reflection part 60 is manufactured.

Furthermore, according to an embodiment of the present disclosure, sincean optical structure, in which a travel path of the light irradiatedfrom the light source 41 is changed such that the light is output, isapplied, an air gap that is an interval between the light source part 40and the reflective surface 61 or between the reflective surface 61 andthe inner lens 70 may be secured to be long. Accordingly, according tothe present disclosure, the light emitted from the light source 41 maybe refracted/ reflected in a specific direction, and thus, diffusion ofthe light may be minimized and optical efficiency may be enhanced.

Meanwhile, the first embodiment of the present disclosure may furtherinclude the inner lens 70. When a direction, in which the lightreflected by the reflection part 60 is output, is defined as an outputdirection D1, the inner lens 70 may be disposed in the output directionD1 of the lens part 50, and the light reflected by the reflection part60 may be output to an outer side.

In detail, the output direction D1 may be a direction, in which thelight reflected by the reflection part 60 is output to an outside, andfor example, when the lamp 10 for a vehicle is a rear lamp, the outputdirection D1 may be a rearward direction with respect to aforward/rearward direction of the vehicle. However, the output directionD1 may be changed to a forward direction or a lateral directionaccording a mounting location of the lamp 10 for a vehicle.

The inner lens 70 may be disposed in the output direction D1 of the lenspart 50, and may output the light that is reflected by the reflectionpart 60 and passes through the lens part 50 to the outside. Although notillustrated, the first embodiment of the present disclosure may furtherinclude an outer lens that is spaced apart from the inner lens 70.

Meanwhile, the present disclosure may further include the housing 20that is installed on a lower side of the reflection part 60.Furthermore, the board part 30, the light source part 40, the lens part50, and the inner lens 70 may be installed between the reflection part60 and the housing 20.

For example, the inner lens 70 may be fixed between the housing 20 andthe reflection part 60. The housing 20 may function to protect the boardpart 30, the light source part 40, the lens part 50, and the inner lens70 by surrounding them, together with the reflection part 60.

Meanwhile, referring to FIG. 1 , the phosphor 63 may be deposited in theentire area of the reflective surface 61. That is, the first embodimentof the present disclosure may implement the phosphor layer 63 bydepositing the phosphor 63 on the entire reflective surface 61 that is asurface that faces the lens part 50 of the reflection part 60.

Accordingly, the reflection part 60 may reflect all the light thatreaches the reflective surface 61 in the output direction D1.

Hereinafter, second to sixth embodiments of the present disclosure willbe described with reference to FIGS. 2 to 18 . The second to sixthembodiments of the present disclosure may be different from the firstembodiment of the present disclosure in the lens part 50 or thereflective surface 61. Accordingly, the second to sixth embodiments ofthe present disclosure may include all of the configurations of thefirst embodiment of the present disclosure, except for theabove-described differences. For example, the second to sixthembodiments of the present disclosure also may include board parts 30 a,30 b, 30 c, 30 d, and 30 e, light source parts 40 a, 40 b, 40 c, 40 d,and 40 e, lens parts 50 a, 50 b, 50 c, 50 d, and 50 e, reflection parts60 a, 60 b, 60 c, 60 d, and 60 e, and configurations thereof, and mayinclude all of the inner lens 70 and housings 20 a, 20 b, 20 c, 20 d,and 20 e.

A shape of the optic 51 a may be variously changed according to anoptical pattern design specification of the applied optical system. Forexample, the optic 51 a may have a shape that extends in aleftward/rightward direction, and a plurality of optics 51 a may becontinuously formed along an upward/downward direction of the reflectivesurface 61 a.

Then, a shape (a vertical cross-section) of the optic 51 a that isperpendicular to an extension direction of the optic 51 a may have asaw-tooth shape that is engaged with the groove 64 a of the reflectivesurface 61 a. An aspect that the groove 64 a is formed to correspond tothe optic 51 a means that the optic 51 a has a shape that is similarthereto to be accommodated in or engaged with the groove 64 a.

Furthermore, for example, the optics 51 a and the grooves 64 a arerepeatedly formed along the upward direction, and the optic 51 a may beformed to become gentler as it goes in the upward direction.Furthermore, the groove 64 a of the reflective surface 61 a also may beformed to be gentler as it goes in the upward direction.

FIG. 9 is aview of a reflection part according to the fourth embodiment of thepresent disclosure, when viewed from a lower side. FIG. 10 is a frontview illustrating the lamp for a vehicle according to the fourthembodiment of the present disclosure, when viewed from a front side.

For example, the reflective groove 62 c may have a hexagonal pyramidshape. A light distribution pattern image may be differentiated byforming the reflective groove 62 c of the hexagonal pyramid shape anddepositing the phosphor 63 c. However, the shape of the reflectivegroove 62 c is not limited thereto.

Fifth Embodiment

FIG. 11 is a cross-sectional view illustrating a lamp for a vehicleaccording to a fifth embodiment of the present disclosure. FIG. 12 is aview of a reflection part according to the fifth embodiment of thepresent disclosure, when viewed from a lower side. FIG. 13 is a frontview illustrating the lamp for a vehicle according to the fifthembodiment of the present disclosure, when viewed from a front side.FIG. 14 illustrates the lamp for a vehicle according to the fifthembodiment of the present disclosure, and is an enlarged view of aportion of FIG. 13 .

Referring to FIGS. 11 to 14 , a lamp 10 d for a vehicle according to afifth embodiment of the present disclosure may include the board part 30d, the light source part 40 d including a plurality of light sources 41d, the lens part 50 d, and the reflection part 60 d including areflective surface 61 d.

Furthermore, the reflective surface 61 d may include a deposition area65 d that is an area, in which the phosphor 63 d is deposited, and anon-deposition area that is the remaining area other than the depositionarea 65 d.

In detail, the deposition area may be formed at a portion of a surfaceof the reflective surface 61 d, which faces the lens part 50 d, and thephosphor 63 d may be deposited to have a specific shape. Among the lightthat is emitted from the light source part 40 d and reaches thereflective surface 61 d, the light that reaches the deposition area 65 dmay be reflected toward the output direction D1. Then, the light thatreaches the deposition area 65 d may have a reflectivity that is higherthan that of the light that reaches the non-deposition area, due to thephosphor 63 d, and may have a color that is different from that of thelight that reaches the non-deposition area.

Accordingly, according to the shape of the deposition area 65 d, animage and a color of the lamp that is irradiated in the output directionD1 may become various. Accordingly, a lamp image having a differentiateddesign may be implemented by forming the deposition area 65 d in astandardized pattern or an atypical shape.

For example, the deposition area 65 d may include a plurality of unitpatterns having a circular shape. However, the present disclosure is notlimited thereto, and the deposition area 65 d may have an elliptical orpolygonal shape.

Furthermore, for example, the deposition area 65 d may include aplurality of pattern groups, and each of the plurality of pattern groupsmay include a plurality of unit patterns having the same size.

Furthermore, the sizes of the unit patterns may become larger as thepattern groups including the unit patterns are located at locations thatare farther from a center of the light source 41 d.

In detail, in the specification, among the unit patterns that form thedeposition area 65 d, the unit patterns disposed within a specificdistance range from the light source 41 d are defined as one patterngroup. Then, the unit patterns included one pattern group may have thesame size.

For example, referring to FIG. 14 , reference numerals 65 d-1, 65 d-2,65 d-3, 65 d-4, 65 d-5, and 65 d-6 denote the pattern groups located atlocations that are farther from the light source 41 d, in a sequencethereof. When the sizes of the unit pattern are compared, it may beidentified that the sizes of the unit patterns become larger as the unitpatterns are located at locations that are farther from the light sourcepart 40 d (65 d-1<65 d-2<65 d-3<65 d-4<65 d-5<65 d-6).

In this way, an amount of the reflected light may be to be smaller bydecreasing deposition of the unit patterns that are closer to the lightsource 41 d, and an amount of the reflected light may be to be larger byincreasing deposition of the unit patterns that are farther from thelight source 41 d. Accordingly, a lamp image having a uniform intensityof light as a whole may be implemented regardless the distances from thelight source 41 d.

The reason why some of the shapes of the unit patterns are viewed as ifthey were not circular but elliptical in FIG. 14 is that it is a viewillustrating the reflective surface 61 d having a curved surface, whenviewed from a lower side.

Sixth Embodiment

FIG. 15 is a cross-sectional view illustrating a lamp for a vehicleaccording to a sixth embodiment of the present disclosure. FIG. 16 is aview of a reflection part according to the sixth embodiment of thepresent disclosure, when viewed from a lower side. FIG. 17 is a frontview illustrating the lamp for a vehicle according to the sixthembodiment of the present disclosure, when viewed from a front side.FIG. 18 illustrates the lamp for a vehicle according to the fifthembodiment of the present disclosure, and is an enlarged view of aportion of FIG. 17 .

Referring to FIGS. 15 to 18 , a lamp 10 e for a vehicle according to asixth embodiment of the present disclosure may include the board part 30e, the light source part 40 e including a plurality of light sources 41e, the lens part 50 e, and the reflection part 60 e including areflective surface 61 e.

Furthermore, the reflective surface 61 e may include a deposition area66 e that is an area, in which the phosphor 63 e is deposited, and anon-deposition area 67 e that is the remaining area other than thedeposition area 66 e.

In detail, the deposition area may be formed at a portion of a surfaceof the reflective surface 61 e, which faces the lens part 50 e, and thephosphor 63 e may be deposited to have a specific shape. Accordingly,according to the shape of the deposition area 66 e, an image and a colorof the lamp that is irradiated in the output direction D1 may becomevarious. Accordingly, a lamp image having a differentiated design may beimplemented by forming the deposition area 66 e in a standardizedpattern or an atypical shape.

For example, the deposition area 66 e may include a plurality of unitpatterns that have a line shape and cross each other to form a latticeshape. Furthermore, the non-deposition area 67 e may include a pluralityof lattice areas by the plurality of unit patterns.

Intervals between adjacent ones of the plurality of unit patterns maybecome larger as they are located at locations that are farther from thelight source 41 e.

In detail, because the size of the deposition area 66 e per unit areaincreases as the distances between the unit pattern having the lineshape becomes smaller, reflectivity may be enhanced. Furthermore,reflectivity may become lower as the size of the deposition area 66 eper unit area becomes smaller. Accordingly, the reflectivity may beadjusted by adjusting the intervals between the adjacent unit patterns.

Accordingly, in the unit patterns having the line shape according to thesixth embodiment, the widths of the unit patterns may be constant (about0.4 mm), and the intervals therebetween may become larger as the unitpatterns are located at locations that are farther from the light source41 e.

For example, FIG. 18 illustrates the intervals d1, d2, d3, and d4between the unit patterns having the line shape, of which distances fromthe light source 41 e. Referring to FIG. 18 , reference numerals d1, d2,d3, and d4 denote intervals between the unit patterns located atlocations that are farther from the light source 41 e in a sequencethereof. When the intervals between the unit patterns are compared, itmay be identified that the intervals between the unit patterns becomelarger as the unit patterns are located at locations that are fartherfrom the light source 41 e (d1<d2<d3<d4).

As an example, when a thickness of the unit pattern having the lineshape is 0.4 mm, d1 may be about 0.7 mm, d2 may be about 1.1 mm, d3 maybe about 2 mm, and d4 may be about 2.6 mm. However, the presentdisclosure is provided for describing an example, and the thicknesses ofand the intervals between the unit patterns having the line shape arenot limited thereto.

The reason why the lattice shape that is the non-deposition area 67 e isviewed as if they were not rectangular but rhombic in FIGS. 16 to 18 isthat the reflective surface 61 e having the curved shape is viewed froma lower side.

According to the embodiment of the present disclosure, the phosphor maybe implemented in the reflection part while not adding any separateprocess by depositing the phosphor on the reflective surface when thereflection part is injection-molded, and the image may be differentiatedby enhancing optical uniformity.

Furthermore, according to the embodiment of the present disclosure,optical patterns having various wavelengths and colors may beimplemented by varying a color of the phosphor deposited on thereflective surface when the reflection part is manufactured.

Furthermore, according to the embodiment of the present disclosure, atravel path of the light emitted from the light source may be controlledby securing the air gap such that the air gap is long, and thus, opticalefficiency may be increased by minimizing diffusion of the light.

According to the embodiment of the present disclosure, the phosphor maybe efficiently implemented without adding a separate process bydepositing the phosphor on the reflective surface when the reflectionpart is injection-molded.

Furthermore, according to an embodiment of the present disclosure, auniformity of the light may be enhanced by depositing the phosphor onthe reflective surface, and images may be differentiated.

Furthermore, according to the embodiment of the present disclosure,optical patterns having various wavelengths and colors may beimplemented by varying a color of the phosphor deposited on thereflective surface when the reflection part is manufactured.

Furthermore, according to an embodiment of the present disclosure,because an optical structure, in which a travel path of the lightirradiated from the light source is changed such that the light isoutput, is applied, an air gap that is an interval between the lightsource part and the reflection surface or between the reflective surfaceand the inner lens may be secured to be long. Accordingly, according tothe present disclosure, the light emitted from the light source 41 maybe refracted and reflected in a specific direction, and thus, diffusionof the light may be minimized and optical efficiency may be enhanced.
